Resuming elective hip and knee arthroplasty after the first phase of the SARS-CoV-2 pandemic: the European Hip Society and European Knee Associates recommendations

Impact of COVID-19 on opioid use in those awaiting hip and knee arthroplasty: a retrospective cohort study

BACKGROUND

COVID-19 has had a detrimental impact on access to hip and knee arthroplasty surgery. We set out to examine whether this had a subsequent impact on preoperative opioid prescribing rates for those awaiting surgery.

METHODS

Data regarding patient demographics and opioid utilisation were collected from the electronic health records of included patients at a large university teaching hospital. Patients on the outpatient waiting list for primary hip and knee arthroplasty as of September 2020 (COVID-19 group) were compared with historical controls (Controls) who had previously undergone surgery. A sample size calculation indicated 452 patients were required to detect a 15% difference in opioid prescription rates between groups.

RESULTS

A total of 548 patients (58.2% female) were included, 260 in the COVID-19 group and 288 in the Controls. Baseline demographics were similar between the groups. For those with data available, the proportion of patients on any opioid at follow-up in the COVID-19 group was significantly higher: 55.0% (143/260) compared with 41.2% (112/272) in the Controls (p=0.002). This remained significant when adjusted for confounding (age, gender, Scottish Index of Multiple Deprivation, procedure and wait time). The proportion of patients on a strong opioid was similar (4.2% (11/260) vs 4.8% (13/272)) for COVID-19 and Controls, respectively. The median waiting time from referral to follow-up was significantly longer in the COVID-19 group compared with the Controls (455 days vs 365 days; p<0.0001).

CONCLUSION

The work provides evidence of potential for an emerging opioid problem associated with the influence of COVID-19 on elective arthroplasty services. Viable alternatives to opioid analgesia for those with end-stage arthritis should be explored, and prolonged waiting times for surgery ought to be avoided in the recovery from COVID-19 to prevent more widespread opioid use.

COVID-19 had Limited Impact on Resumption of Elective Joint Arthroplasty and Ethnic Disparities

In response to the COVID-19 pandemic, federal and state recommendations included the postponement of elective arthroplasties until adequate safety measures could be implemented. Following resumption of arthroplasties, exposure fears and financial concerns may have restricted access for some demographics. Therefore, the purpose of this study was to (1) investigate how the COVID-19 pandemic impacted the incidence of arthroplasty, both overall and by various demographics, and (2) evaluate if pre-operative patient-reported measures were different throughout the pandemic. Data were collected prospectively as part of an on-site joint registry between January 2019 and April 2021. Phase 1 (N=518) included all patients prior to the cancelation of elective procedures (average 36 cases/month), Phase 2 (N=121) was defined from restart until monthly caseload met/surpassed the average Phase 1 caseload (5 months), and Phase 3 (N=277) included all remaining cases. Multiple analysis of variance and chi-squared tests were performed to compare patient demographics and outcomes between phases. No significant differences were noted in patient demographics, with the exception of a decrease in Native Hawaiian/Pacific Islander patients and an increase in Asian patients during Phase 2 (P =.004). Length of stay decreased for unilateral arthroplasty from Phase 1 (0.9±1.1 days) to Phase 2 (0.4±0.6 days) and Phase 3 (0.6±0.7 days) (P <.001), while pre-operative patient reported outcomes remained similar across the 3 time periods. By implementing proper safety measures, the current orthopedic center achieved a timely recovery with no long-lasting inconsistencies in patient cohorts upon resumption of arthroplasties.

Omicron, Long-COVID, and the Safety of Elective Surgery for Adults and Children: Joint Guidance from the Therapeutics and Guidelines Committee of the Surgical Infection Society and the Surgery Strategic Clinical Network, Alberta Health Services

Background: Active and recent coronavirus disease 2019 (COVID-19) infections are associated with morbidity and mortality after surgery in adults. Current recommendations suggest delaying elective surgery in survivors for four to 12 weeks, depending on initial illness severity. Recently, the predominant causes of COVID-19 are the highly transmissible/less virulent Omicron variant/subvariants. Moreover, increased survivability of primary infections has engendered the long-COVID syndrome, with protean manifestations that may persist for months. Considering the more than 600,000,000 COVID-19 survivors, surgeons will likely be consulted by recovered patients seeking elective operations. Knowledge gaps of the aftermath of Omicron infections raise questions whether extant guidance for timing of surgery still applies to adults or should apply to the pediatric population. Methods: Scoping review of relevant English-language literature. Results: Most supporting data derive from early in the pandemic when the Alpha variant of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) predominated. The Omicron variant/subvariants generally cause milder infections with less organ dysfunction; many infections are asymptomatic, especially in children. Data are scant with respect to adult surgical outcomes after Omicron infection, and especially so for pediatric surgical outcomes at any stage of the pandemic. Conclusions: Numerous knowledge gaps persist with respect to the disease, the recovered pre-operative patient, the nature of the proposed procedure, and supporting data. For example, should the waiting period for all but urgent elective surgery be extended beyond 12 weeks, e.g., after serious/critical illness, or for patients with long-COVID and organ dysfunction? Conversely, can the waiting periods for asymptomatic patients or vaccinated patients be shortened? How shall children be risk-stratified, considering the distinctiveness of pediatric COVID-19 and the paucity of data? Forthcoming guidelines will hopefully answer these questions but may require ongoing modifications based on additional new data and the epidemiology of emerging strains.

Telerehabilitation has similar clinical and patient-reported outcomes compared to traditional rehabilitation following total knee arthroplasty

PURPOSE

Telehealth rehabilitation (telerehab) is an increasingly popular cost-saving alternative to traditional rehabilitation after total joint arthroplasty. We compared the safety and efficacy of an institutional telerehab program to conventional "face-to-face" rehabilitation in a sample of patients undergoing total knee arthroplasty (TKA).

METHODS

A retrospective matched cohort study was performed. Medicare patients who utilized telerehab following unilateral TKA were matched in a 1:3 ratio to those utilizing conventional rehabilitation. Patients were matched on sex, body mass index (BMI, ± 5 kg/m2), preoperative extension (± 10 degrees), preoperative flexion (± 10 degrees), and Risk Assessment and Prediction Tool (RAPT) score (± 2 points). Ninety-day unplanned healthcare encounters, 120-day manipulations under anesthesia (MUAs), and 6-week and 3-month changes in the Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR), pain visual analog scale (VAS), Veterans RAND 12 (VR-12), and Lower-Extremity Activity Scale (LEAS) were compared between groups.

RESULTS

Eighty-two telerehab patients and 244 conventional rehab patients were included. After matching, there were no differences in 90-day unplanned healthcare encounters or 120-day MUA rates between groups. There were no differences in 6-week or 3-month changes in KOOS-JR, VAS pain, or VR-12 mental or physical sub-scores between groups. Telerehab patients had a greater improvement in LEAS score at 3 months compared to the conventional group (mean difference 1.9, P = 0.03).

CONCLUSION

In a matched cohort study of 326 TKA patients, telerehab patients had similar rates of unplanned healthcare encounters and MUAs and similar patient-reported outcomes compared to conventional PT patients, suggesting that telerehab can be an equally effective alternative to conventional PT following TKA.

Second and Third Pandemic Waves in Apulia: How COVID-19 Affected Orthopedic and Trauma Care-A Single-Center Study

PURPOSE

In orthopedics and traumatology, as a direct consequence of the COVID-19 first wave, there was a massive reorganization and a stop to all elective activities, which were postponed. In this study, we aimed to analyze the impact of the COVID-19 pandemic on orthopedic surgery in Apulia during the second wave, from March to June 2021 (when Apulia was under social distancing restrictions), and during the third wave, from September to December 2021 (when Apulia was under no restrictions). We compared these months to the same periods in 2019 for an evaluation of the surgical decrease during the pandemic period.

METHODS

We performed a retrospective analysis of major orthopedic procedures, day-surgery procedures and urgent procedures (trauma and non-traumatic amputation) performed during the second and third waves of the pandemic in our clinic, and we compared these data with the same procedures performed in the corresponding periods of 2019, before the pandemic.

RESULTS

Surgical activity was significantly decreased during both periods; the only increase in surgical activity in 2021 compared to 2019 was in total hip, knee and shoulder arthroplasty, with a surge of +7.69% registered in the period September-December 2021.

CONCLUSIONS

Longer waiting lists and limited healthcare resources were the big challenges for the orthopedic community, and they still represent a substantial issue to confront today.

Making a Joint Decision Regarding the Timing of Surgery for Elective Arthroplasty Surgery After Being Infected With COVID-19: A Systematic Review

BACKGROUND

The Coronavirus Disease 2019 (COVID-19) pandemic has caused a substantial number of patients to have their elective arthroplasty surgeries rescheduled. While it is established that patients with COVID-19 who are undergoing surgery have a significantly higher risk of experiencing postoperative complications and mortality, it is not well-known at what time after testing positive the risk of postoperative complications or mortality returns to normal.

METHODS

PubMed (MEDLINE), Excerpta Medica dataBASE, and professional society websites were systematically reviewed on March 7, 2022 to identify studies and guidelines on the optimal timeframe to reschedule patients for elective surgery after preoperatively testing positive for COVID-19. Outcomes included postoperative complications such as mortality, pneumonia, acute respiratory distress syndrome, septic shock, and pulmonary embolism.

RESULTS

A total of 14 studies and professional society guidelines met the inclusion criteria for this systematic review. Patients with asymptomatic COVID-19 should be rescheduled 4-8 weeks after testing positive (as long as they do not develop symptoms in the interim), patients with mild/moderate COVID-19 should be rescheduled 6-8 weeks after testing positive (with complete resolution of symptoms), and patients with severe/critical COVID-19 should be rescheduled at a minimum of 12 weeks after hospital discharge (with complete resolution of symptoms).

CONCLUSIONS

Given the negative association between preoperative COVID-19 and postoperative complications, patients should have elective arthroplasty surgery rescheduled at differing timeframes based on their symptoms. In addition, a multidisciplinary and patient-centered approach to rescheduling patients is recommended. Further study is needed to examine the impact of novel COVID-19 variants and vaccination on timeframes for rescheduling surgery.

The Efficacy of Pre-Operative Self-Isolation Guidelines for Safe Elective Orthopaedic Surgeries: A Prospective Pilot Study

Objectives

This study aimed to determine the efficacy of the self-isolation guidance for elective orthopaedic surgery. We aimed to evaluate the relationship between patient compliance with the self-isolation guidance and the resulting COVID-19 status. This would give planning strategies for managing elective orthopaedic lists.

Method

For the study, 110 patients who underwent elective orthopaedic surgical procedures during a one-month period were identified. Patients scheduled for surgery were asked to take a SARS-CoV-2 PCR test three days prior to surgery and they were asked to follow the self-isolation guidance. On the day of admission, patients declared compliance with self-isolation regulations. Admission was refused in cases of non-compliance. After discharge, telephone calls were made to patients to determine the degree of compliance with the self-isolation guidance.

Results

Overall, 106 out of 107 patients that were compliant with the self-isolation guidance tested negative for COVID-19; 15 patients had their operation cancelled over the one-month period; of which one-third were cancelled by the patients themselves. Three patients were found to be non-compliant with the self-isolation guidance. Of these three non-compliant patients, one tested positive for COVID-19. Adherence to the self-isolation guidelines helped to prevent last-minute cancellations and manage the list effectively.

Conclusions

Compliance with our self-isolation guidance accompanied by PCR screening minimises the risk of testing positive for COVID-19 and is thus an effective system to safely perform elective orthopaedic surgery. Intentionally overbooking theatre lists by 10 to 12.5% may account for cancellations and improve theatre efficiencies during post-pandemic recovery plans for elective orthopaedic surgeries.

Effect of the COVID-19 Pandemic on Rates of Ninety-Day Peri-Prosthetic Joint and Surgical Site Infections after Primary Total Joint Arthroplasty: A Multicenter, Retrospective Study

Background: The impact of the coronavirus 2019 (COVID-19) pandemic on the rate of primary total joint arthroplasty (TJA) peri-prosthetic joint infection (PJI) and superficial surgical site infections (SSI) is currently unknown. The purpose of this multicenter study was to evaluate any changes in the rates of 90-day PJI or 30-day SSI, including trends in microbiology of the infections, during the COVID-19 pandemic compared to the three years prior. Patients and Methods: An Institutional Review Board-approved, multicenter, retrospective study was conducted with five participating academic institutions across two healthcare systems in the northeastern United States. Primary TJA patients from the years 2017-2019 were grouped as a pre-COVID-19 pandemic cohort and patients from the year 2020 were grouped as a COVID-19 pandemic cohort. Differences in patient demographics, PJI, SSI, and microbiology between the two cohorts were assessed. Results: A total of 14,844 TJAs in the pre-COVID-19 pandemic cohort and 5,453 TJAs in the COVID-19 pandemic cohort were evaluated. There were no substantial differences of the combined 90-day PJI and 30-day superficial SSI rates between the pre-COVID-19 pandemic cohort (0.35%) compared with the COVID-19 pandemic cohort (0.26%; p = 0.303). Conclusions: This study did not find any change in the rates of 90-day PJI or 30-day superficial SSI in patients undergoing primary TJA between a pre-COVID-19 pandemic and COVID-19 pandemic cohort. Larger national database studies may identify small but substantial differences in 90-day PJI and 30-day superficial SSI rates between these two time periods. Our data may support continued efforts to maintain high compliance with hand hygiene, use of personal protective equipment, and limited hospital visitation whenever possible.

Immuno-Thrombotic Complications of COVID-19: Implications for Timing of Surgery and Anticoagulation

Early in the coronavirus disease 2019 (COVID-19) pandemic, global governing bodies prioritized transmissibility-based precautions and hospital capacity as the foundation for delay of elective procedures. As elective surgical volumes increased, convalescent COVID-19 patients faced increased postoperative morbidity and mortality and clinicians had limited evidence for stratifying individual risk in this population. Clear evidence now demonstrates that those recovering from COVID-19 have increased postoperative morbidity and mortality. These data-in conjunction with the recent American Society of Anesthesiologists guidelines-offer the evidence necessary to expand the early pandemic guidelines and guide the surgeon's preoperative risk assessment. Here, we argue elective surgeries should still be delayed on a personalized basis to maximize postoperative outcomes. We outline a framework for stratifying the individual COVID-19 patient's fitness for surgery based on the symptoms and severity of acute or convalescent COVID-19 illness, coagulopathy assessment, and acuity of the surgical procedure. Although the most common manifestation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is COVID-19 pneumonitis, every system in the body is potentially afflicted by an endotheliitis. This endothelial derangement most often manifests as a hypercoagulable state on admission with associated occult and symptomatic venous and arterial thromboembolisms. The delicate balance between hyper and hypocoagulable states is defined by the local immune-thrombotic crosstalk that results commonly in a hemostatic derangement known as fibrinolytic shutdown. In tandem, the hemostatic derangements that occur during acute COVID-19 infection affect not only the timing of surgical procedures, but also the incidence of postoperative hemostatic complications related to COVID-19-associated coagulopathy (CAC). Traditional methods of thromboprophylaxis and treatment of thromboses after surgery require a tailored approach guided by an understanding of the pathophysiologic underpinnings of the COVID-19 patient. Likewise, a prolonged period of risk for developing hemostatic complications following hospitalization due to COVID-19 has resulted in guidelines from differing societies that recommend varying periods of delay following SARS-CoV-2 infection. In conclusion, we propose the perioperative, personalized assessment of COVID-19 patients' CAC using viscoelastic hemostatic assays and fluorescent microclot analysis.

Is it time to resume elective knee arthroplasty surgery? A multidisciplinary experience in a Sardinian center during the SARS-CoV-2 pandemic

Background

Starting in January 2020, the SARS-CoV-2 pandemic caused changes in the nation's health systems. The hospital's reorganization led to a near-total stop of non-urgent, elective surgeries across all specialties, including hip and knee arthroplasty. However, in May 2020, a gradual elective surgery restarting was possible. Considering the risk of COVID-19 infections, the European Knee Associates suggest the need to implement specific protocols for a safe return to orthopaedic elective surgery.

Methods

A retrospective analysis regarding all patients who underwent primary knee arthroplasty (TKA) between March 1st and October 1st, 2020 using an institutional database was performed. The study time was divided into 2 periods: Pandemic (from March 2020 to May 2020), Post Pandemic (from June 2020 to October 2020). A specific protocol was designed to safeguard the health of patients and healthcare workers during the SARS-CoV-2 pandemic.

Results

A total of 147 patients underwent total knee replacement surgery in the analyzed period. The mean surgical time was 77.6 (+/-18.9). The intraoperative mean blood loss was 54 (+/-28) ml. The mean hospital stay was 3-4 days. Among the treated patients no case of COVID-19 infection was observed.

Conclusion

The use of our protocol, developed ad hoc for the management of elective orthopedic patients, allowed the restart of elective orthopedic surgery in a safe and reproducible way with an average increase of 374% on surgical activity between the pandemic and post-pandemic periods without record cases of contagion among the treated patients.

Standardized perioperative practice in surgery during the covid-19 pandemic: a narrative review of the evidences

INTRODUCTION

The Coronavirus (Covid-19) pandemic activated a global health crisis. The best practice in operating room is a discussed argument. This review was performed to clarify the importance and effectiveness of standardized clinical practice (procedure, organization, guidance), identifying contemporary evidence deduced from some international experience. We decided to make a narrative review that analyses the most current shared guidelines and procedures in management of Covid-19 patients in perioperative theatre.

EVIDENCE ACQUISITION

Medline was searched using PubMed (from 1 April 2020 to 22 December 2020) for relevant study according with Prisma Guidelines. The studies were assessed and classified for levels of evidence and recommendation. Three factors were extracted: operating room organization, personnel safety and procedures.

EVIDENCE SYNTHESIS

44 articles were identified: eleven met eligibility criteria: of these , four articles are expert opinion/experience/descriptive study, one is a multicentre/descriptive study and six are review/systematic review. 33 articles were excluded because didn't meet inclusion criteria. The studies selection is focused on clinical processes in the operating theatre, guidelines for the Operating Room safety, correct procedures for Personal Protective Equipement use, experience and recommendations related to COVID-19 context.

CONCLUSIONS

despite the modest number of studies and high-evidence, all the publications show agreement about many aspects of Operating Room practice. Global experiences selection confirms the role and the importance of a standardized practice in operating theatre instead personal interpretation; this study aims to provide a guidelines qualitative synthesis for all surgical staff, enclosing basic behaviours for the staff and patient safety in a complex assistant approach on a pandemic time.

Preoperative patients' health decrease moderately, while hospital costs increase for hip and knee replacement due to the first COVID-19 lockdown in Germany

PURPOSE

The purpose of this study was a comparison between osteoarthritis patients with primary hip and knee replacements before, during and after the first COVID-19 lockdown in Germany. Patients' preoperative health status is assumed to decrease, owing to delayed surgeries. Costs for patients with osteoarthritis were assumed to increase, for example, due to higher prices for protective equipment. Hence, a comparison of patients treated before, during and after the first lockdown is conducted.

METHODS

In total, 852 patients with primary hip or knee replacement were included from one hospital in Germany. Preoperative health status was measured with the WOMAC Score and the EQ-5D-5L. Hospital unit costs were calculated using a standardised cost calculation. Kruskal-Wallis tests and Chi-squared tests were applied for the statistical analyses.

RESULTS

The mean of the preoperative WOMAC Score was slightly higher (p < 0.01) for patients before the first lockdown, compared with patients afterwards. Means of the EQ-5D-5L were not significantly different regarding the lockdown status (NS). Length of stay was significantly reduced by approximately 1 day (p < 0.001). Total inpatient hospital unit costs per patient and per day were significantly higher for patients during and after the first lockdown (p < 0.001).

CONCLUSION

Preoperative health, measured with the WOMAC Score, worsened slightly for patients after the first lockdown compared with patients undergoing surgery before COVID-19. Preoperative health, measured using the EQ-5D-5L, was unaffected. Inpatient hospital unit costs increased significantly with the COVID-19 pandemic.

Both younger and elderly patients in pain are willing to undergo knee replacement despite the COVID-19 pandemic: a study on surgical waiting lists

PURPOSE

To identify factors influencing patient's availability to re-schedule primary total knee replacement (TKR) or revision (RKR) surgery after the lockdown (March-May 2020) during the COVID-19 pandemic.

METHODS

A prospective cohort study through a telephone survey was performed in 156 patients (143 for primary and 13 for revision) included in the TKR and RKR surgical waiting list before March 2020. Contact of each patient with COVID-19, stress and anxiety, perceived pain, and function were obtained in the interviews, and also the preference of each patient to have re-scheduled surgery (early or late). Finally, we registered their response (acceptance or refusal) when surgery was effectively re-scheduled.

RESULTS

88 out of 156 patients waiting for knee replacement (76/143 of those waiting for TKR, 12/13 of those waiting for RKR) declared themselves ready for surgery in less than 1 month. When re-scheduled, 115 patients underwent surgery and 41 refused. Significantly different preferences were found for age (more prone to surgery if under 65), revision surgery (more readily available), pain (7.9 ± 1.7/10 in NRS in those undergoing surgery, 5.6 ± 2.3/10 in those refusing, p = 0.000), or COVID-19 diagnosis, but not other close contact with COVID-19, comorbidities, stress, or anxiety. A logistic regression model confirmed that revision surgery (OR 9.33), perceived severe pain (OR 5.21), and age under 65 years (OR 5.82) were significantly associated with patient preference. The probability of patients over 65 to prefer early surgery reached 60% only with pain at or above 9/10.

CONCLUSIONS

Surgical timing preferences for knee replacement vary between patients older than 65 years (immediate surgery only when pain is intense) and younger patients (immediate surgery no matter the amount of pain). Even if COVID-19 severely stroke our population, the need for knee replacement stood in the young population and even in the aged population at risk for COVID when pain was important.

Comparing ERAS-outpatient versus standard-inpatient hip and knee replacements: a mixed methods study exploring the experience of patients who underwent both

BACKGROUND

Optimizing patients' total hip and knee arthroplasty (THA/TKA) experience is as crucial for providing high quality care as improving safety and clinical effectiveness. Yet, little evidence is available on patient experience in standard-inpatient and enhanced recovery after surgery (ERAS)-outpatient programs. Therefore, this study aimed to gain a more in-depth understanding of the patient experience of ERAS-outpatient programs in comparison to standard-inpatient programs.

METHODS

We conducted a convergent mixed methods study of 48 consecutive patients who experienced both standard-inpatient and ERAS-outpatient THA/TKA contralaterally. A reflective thematic analysis was conducted based on data collected via a questionnaire. Bivariate correlations between the patient experience and patients' characteristics, clinical outcomes and care components satisfaction were performed. Then, the quantitative and qualitative data were integrated together.

RESULTS

The theme Support makes the difference for better and for worse was identified by patients as crucial to their experience in both joint replacement programs. On the other hand, patients identified 3 themes distinguishing their ERAS-outpatient from their standard-inpatient experience: 1) Minimizing inconvenience, 2) Home sweet home and 3) Returning to normal function and activities. Potential optimization expressed by patients were to receive more preoperative information, additional postoperative rehabilitation sessions, and ensuring better coherence of care between hospital and home care teams. Weak to moderate positive and statistically significant correlations were found between patients' THA/TKA experience and satisfaction with pain management, hospital stay, postoperative recovery, home care, and overall results (rs = + [0.36-0.66], p-value < 0.01).

CONCLUSION

Whatever the perioperative program, the key to improving patients' THA/TKA experience lies in improving support throughout the care episode. However, compared to standard-inpatient care, the ERAS-outpatient program improves patients' experience by providing dedicated support in postoperative care, reducing postoperative inconvenience, optimizing pain management, returning home sooner, and recovering and regaining function sooner. Patients' THA/TKA experience could further be enhanced by optimizing the information provided to the patient, the rehabilitation program and the coherence between care teams.

Effects of the COVID-19 Pandemic on the Epidemiology of Knee and Shoulder Arthroscopy

The purpose of our study was to comprehensively assess the effect of the COVID-19 pandemic on knee and shoulder arthroscopy performed in an orthopedic department of a university hospital in Poland. This study compared the data on all shoulder and knee arthroscopy procedures performed in two different periods: The period of the COVID-19 pandemic in Poland (from March 4, 2020, to October 15, 2020) and the corresponding period prior to the pandemic (March 4, 2019, to October 15, 2019). The study evaluated epidemiological data, demographic data, and hospital stay duration. The total number of arthroscopy procedures conducted in the evaluated period in 2020 was approximately 8.6% higher than that in the corresponding 2019 period. The mean duration of hospital stay for orthopedic patients after their knee or shoulder arthroscopy was 3.1 days in 2020 and 2.8 days in 2019. Our study revealed the mean age of arthroscopy patients during the pandemic to be lower at 48.4 years than the 51.2 years recorded in 2019. The male-to-female ratio was shown to be lower at .85 during the pandemic, having decreased from 1.5 in 2019. The COVID-19 pandemic did not reduce the number of arthroscopy performed at our center, and the mean age of the patients did not change. However, the pandemic had a marked effect on the mean duration of hospital stay and male-to-female ratio.

No difference in 13-year survival after medial pivot or central pivot mobile bearing total knee arthroplasty. A propensity matched comparative analysis

PURPOSE

The present study was designed to evaluate the long-term results (more than 10 years) of mobile bearing total knee arthroplasty (TKA) and to compare the survival of medial pivot axis (MPA) and central pivot axis (CPA) TKAs. The primary hypothesis was that the 10- to 15-year survival rate of MPA TKAs will be better than CPA TKAs.

METHODS

A national, multicenter, retrospective study was performed in France. In this case-control design, 1154 TKAs were paired into the CPA group (control group: 577 cases) and MPA group (study group: 577 cases) based on a logistic regression analysis of age, gender, body mass index and severity of the coronal deformity, defining the propensity score for each case. Final survival information follow-up was obtained for 946 cases (82%).

RESULTS

There was no significant difference between the control and study groups for any baseline data. Twenty-two prosthetic revisions (2%) were performed for mechanical reasons during the follow-up period. There was no significant difference between the 13-year survival rates of CPA (98%) and MPA (97%) TKAs. There was no significant difference between groups in their final Oxford and Knee Society scores.

CONCLUSION

Our findings do not support the assumption that medialization of the pivot axis of a mobile bearing TKA improves clinical results or survival.

Features of hospitalization of patients in the trauma and orthopedic center in the context of the second wave of the COVID-19 pandemic

The algorithm for examining patients for SARS-CoV-2 during admission to non-infectious hospitals, a unified route scheme for patients taking into account the potential infectious hazard is not regulated.

The aim of the study is to identify the features of the diagnosis of SARS-CoV-2 during planned hospitalization in the field of “traumatology and orthopedics”; to present schemes for examining patients for SARS-CoV-2 during hospitalization and patient routing in the clinic.

Materials and methods. The route and procedure of examination to exclude the nosocomial spread of COVID-19 in patients hospitalized for three months is described. 3366 survey results were analyzed.

Results. Positive PCR tests for COVID-19 before hospitalization were obtained in 4.5 % of patients. High titers of IgM are found in 7.8 % of cases. At the level of the Pass Office, 10.5 % of arrivals were denied hospitalization. The CT scan of the chest organs, which was then carried out, revealed among the examined 9.1 % of asymptomatic pneumonia, of which 93.5 % – with radiological signs of COVID-19, 2/3 of “covid” pneumonia – with a CT-0 degree. Another part of hospitalizations was postponed due to somatic contraindications during clinical examination. After all the selection stages, 73.2 % of planned hospitalizations ended up. In the hospital, 12 cases of COVID-19 were detected in the postoperative period, more often on the 4th day after the operation. A total of 2,328 patients were discharged during the study period – 69.2 % of planned hospitalizations, a third of patients received a medical withdrawal from hospitalization due to COVID-19.

Conclusions. The peculiarities of admitting patients to planned hospitalization in the traumatology and orthopedics profile is the difficulty of reliably detecting COVID-19 in a limited time. In some cases of asymptomatic course, the disease is detected only with the help of CT diagnostics. In 0.5 % of cases, COVID-19 is detected in the postoperative period. The described patient routing scheme, multistage diagnostics to exclude COVID-19 are able to ensure maximum infectious safety of patients and staff in the clinic.

The Effect of the COVID-19 Pandemic on Total Hip and Knee Arthroplasty Surgical Volume in 2020 in Poland

The aim of this study was to analyse the effect of the first year of the COVID-19 pandemic on total hip arthroplasty (THA) and total knee arthroplasty (TKA) surgical volume in Poland. A retrospective analysis of data concerning THA and TKA collected by the National Health Fund in Poland in 2019 and in 2020 has been conducted. The number of primary hip or knee arthroplasties in 2020 was around 71% and 67% of the number registered in 2019, respectively. There was also a decline in the volume of revision arthroplasties observed, with 65% and 63% of THA and TKA revisions performed in 2019. The most significant decrease was observed in April and May, and during the second wave of the pandemic in November 2020, with a decline of 87%, 55% and 56%, respectively. The results of this study show the significant impacts that the COVID-19 pandemic had on the volume of elective hip and knee arthroplasties in Poland in 2020. In comparison with 2019, a decrease of around 30% for primary and of 40% for revision arthroplasties was observed. The most significant decline was observed in April and May 2020, and during the second wave of the COVID-19 pandemic in Poland in November 2020.

A seven week observational analysis of clinical activities in a North Italian orthopaedic hospital during the second wave of SARS-CoV-2 pandemic: far from usual volumes, but different from the first wave

Purpose

We previously described the radical changes occurred in an orthopaedic hospital in Milan (Italy) during the first SARS-CoV-2 pandemic outbreak. Currently, during the second wave, the situation is still far from normality. Here we describe the changes that took place, and are still ongoing, in the clinical practice.

Methods

Number and type of admissions, outpatients activity, ER and urgent procedures in SARS-CoV-2 negative and positive patients have been analyzed over seven weeks (October 26th–December 13th, 2020) and compared with the correspondent period in 2019 and the same timeframe during the first wave (February 24th–April 10th).

Results

2019 vs. 2020: Overall admissions decreased by 39.8%; however, while admissions for elective surgery dropped by 42.0%, urgent surgeries increased by 117.0%. Rehabilitation admissions declined by 85.2%. White and green priority ER consultations declined by 41.6% and 52.0%, respectively; yellow and red increased by 766.7% and 400.0%, respectively.

Second vs. first wave: Overall admissions increased by 58.6% with a smoother decrement in weekly admissions than during the first wave.

Disparity of acute admissions vs. rehabilitation expanded: Acute cases increased by 63.6% while rehabilitation cases decreased by 8.7%. Admissions to triage procedures increased by 72.3%.

Conclusions

Activity levels are far from normality during the second COVID-19 wave. Elective surgery and outpatients-related activities are still strongly limited compared to 2019 while the number of urgent cases treated increased consistently. SARS-CoV-2 positive emergencies are slightly higher than during the first wave. These important changes are expected to impact on health service and hospital budget for long.

Self-quarantine programme and pre-operative SARS-CoV-2 PCR screening for orthopaedic elective surgery: experience from Japan

PURPOSE

This study aimed to evaluate the acceptability of 14 days of self-quarantine and the positivity rate of pre-operative severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) screening for patients undergoing elective orthopaedic surgery.

METHODS

The self-quarantine programme and pre-operative SARS-CoV-2 PCR screening were initiated for patients who were scheduled for admission later than 7 May 2020 for elective orthopaedic surgery on admission. On the day of admission, the patients declared compliance with self-quarantine regulations. The admission was refused in cases of non-compliance. After admission, the patients underwent SARS-CoV-2 PCR screening. If PCR results were negative, isolation was terminated. If PCR results were positive, the surgery was postponed. If the patients had symptoms suspicious of coronavirus disease (COVID-19) after surgery, the PCR test was repeated.

RESULTS

Overall, 308 patients (age: 63.2 ± 18.8 years, 197 female and 111 male) were scheduled for elective orthopaedic surgery. Two patients did not agree with the requirements of self-quarantine, and two other procedures were cancelled. No non-compliance was reported; thus, the completion rate of the self-quarantine programme was 304/308 (98.7%). Finally, 304 patients underwent PCR testing, and there were no positive PCR results. After cancellations of four operations due to reasons other than COVID-19, 300 surgical procedures were performed. No patients developed COVID-19 during hospitalisation.

CONCLUSIONS

Although this system is based on trusting the good behaviour of patients, accompanied by PCR screening, we believe that the results showed the efficacy of the system in safely performing orthopaedic surgery during the COVID-19 pandemic.

The Epidemiology of Hip and Knee Primary and Revision Arthroplasties during the COVID-19 Pandemic

BACKGROUND

The purpose of this study was to provide a comprehensive assessment of the impact of the COVID-19 pandemic on the epidemiology of primary and revision arthroplasties of the hip and knee joint.

METHODS

This study compared the data on knee and hip arthroplasty procedures from 2 hospitals (primary and revision) conducted in two periods: the period of the COVID-19 pandemic in Poland (from 4 March 2020 to 15 October 2020) and the corresponding period prior to the pandemic (from 4 March 2019 to 15 October 2019). We compared the epidemiological data, demographic data, and hospital stay duration data from these two periods.

RESULTS

Our analysis demonstrated that the total number of hip arthroplasties conducted in 2020 decreased by 26% in comparison with 2019. In the case of knee arthroplasties, the total number of procedures in the evaluated period in 2020 decreased by 44%. Our study also showed that the mean time of hospital stay for orthopedic patients following hip or knee arthroplasty was 22.87% shorter. The female-to-male patient ratio decreased between the analyzed periods, and this was 22.96% lower during the pandemic.

CONCLUSION

The COVID-19 pandemic in these two hospitals in Poland led to reduced numbers of hip and knee replacement procedures, shorter hospital stays, and a decreased female-to-male patient ratio. The mean age of patients undergoing hip or knee arthroplasty remained unchanged during the national lockdown with respect to the pre-pandemic figure.

Hintergrund

In der COVID-19-Pandemie ging die Versorgung nichtübertragbarer Erkrankungen zeitweise deutlich zurück, auch weil Menschen Angst vor einer Ansteckung hatten. Wir führen eine Bestandsaufnahme zur organisationalen Gesundheitskompetenz in der Regelversorgung nichtübertragbarer Erkrankungen in der ersten Welle der COVID-19-Pandemie durch und fragen: Inwiefern wurden Menschen mit gesundheitlichen Beschwerden dabei unterstützt, gesundheitskompetente Entscheidungen für oder gegen die Inanspruchnahme von Versorgungsleistungen zu treffen?

Methodik

Strukturierende Inhaltsanalyse der Internetpräsenzen der Mitglieder der Arbeitsgemeinschaft der Wissenschaftlich Medizinischen Fachgesellschaften (AWMF; n = 179), der kassen(zahn)ärztlichen Vereinigungen (K(Z)Ven; n = 38), ausgewählter Krankenkassen (n = 21), ausgewählter Behandlungseinrichtungen (n = 25) und überregionaler Anbieter von Gesundheitsinformationen (n = 5) zu Informationen und Angeboten zum Thema.

Ergebnisse

Die geprüften Internetpräsenzen informieren weitgehend rund um COVID-19, aber nur selten darüber, wie man sich bei einer (vermuteten) anderen Erkrankung in Bezug auf die Inanspruchnahme von Versorgungsleistungen verhält. 2 Portale von Anbietern von Gesundheitsinformationen, eine Krankenkasse, aber keine der KVen bieten explizite Entscheidungshilfen an. KVen weisen öfter, aber nicht durchgängig auf die generelle Möglichkeit von Videosprechstunden hin.

Diskussion

Für die meisten Patient*innen gab es damit keine gezielten Informationen zu dem Thema. Angesichts der Fortdauer der COVID-19-Pandemie gilt es, vorhandene vertrauenswürdige, qualitativ hochwertige Informations- und Beratungskapazitäten auszubauen und ihre Bekanntheit zu erhöhen, um gesundheitskompetente Entscheidungen auch in der Pandemie zu ermöglichen.

Enhanced Recovery after Surgery (ERAS) for Hip and Knee Replacement-Why and How It Should Be Implemented Following the COVID-19 Pandemic

The COVID-19 pandemic has led to a reduction in hip and knee replacement surgery across healthcare systems. When regular operating returns, there will be a large volume of patients and an emphasis on a short hospital stay. Patients will be keen to return home, and capacity will need to maximised. Strategies to reduce the associated risks of surgery and to accelerate recovery will be needed, and so Enhanced Recovery after Surgery (ERAS) should be promoted as the model of care. ERAS protocols are proven to reduce hospital stay safely; however, ERAS pathways may require adaption to ensure both patient and staff safety. The risk of exposure to possible sources of COVID-19 should be limited, and so hospital visits should be minimised. The use of technology such as smartphone apps to provide pre-operative education, wearable activity trackers to assist with rehabilitation, and the use of telemedicine to complete outpatient appointments may be utilised. Also, units should be reminded that ERAS protocols are multi-modal, and every component is vital to minimise the surgical stress response. The focus should be on providing better and not just faster care. Units should learn from the past in order to expedite the implementation of or adaption of existing ERAS protocols. Strong leadership will be required, along with a supportive organisational culture, an inter-professional approach, and a recognised QI method should be used to contextualize improvement efforts.

COVID-19-related cancellation of elective orthopaedic surgery caused increased pain and psychosocial distress levels

PURPOSE

Health care systems in most European countries were temporarily restructured to provide as much capacity as possible for the treatment of coronavirus disease 2019 (COVID-19) patients. Subsequently, all elective surgeries had to be cancelled and postponed for months. The aim of the present study was to assess the pretreatment health status before and after COVID-19-related cancellation and the psychosocial distress caused by the cancellation.

METHODS

For this study, a questionnaire was developed collecting sociodemographic data and information on health status before and after the cancellation. To assess psychosocial distress, the validated depression module of the Patient Health Questionnaire (PHQ-9), was implemented. PHQ-9-Scores of 10 and above were considered to indicate moderate or severe depressive symptoms. In total, 119 patients whose elective orthopaedic surgery was postponed due to the COVID-19 pandemic were surveyed once at least 8 weeks after the cancellation.

RESULTS

Seventy-seven patients (65%; 34 female, 43 male) completed the questionnaire and were included. The predominant procedures were total knee arthroplasty (TKA), hip arthroscopy and foot and ankle surgery. The mean pain level significantly increased from 5.5 ± 2.2 at the time of the initially scheduled surgery to 6.2 ± 2.5 at the time of the survey (p < 0.0001). The pain level before cancellation of the surgery was significantly higher in female patients (p = 0.029). An increased analgetic consumption was identified in 46% of all patients. A mean PHQ-9 score of 6.1 ± 4.9 was found after cancellation. PHQ-9 scores of 10 or above were found in 14% of patients, and 8% exhibited scores of 15 points or above. Significantly higher PHQ-9 scores were seen in female patients (p = 0.046). No significant differences in PHQ-9 scores were found among age groups, procedures or reasons for cancellation.

CONCLUSION

Cancellation of elective orthopaedic surgery resulted in pain levels that were significantly higher than when the surgery was scheduled, leading to increased analgesic use. Additionally, significant psychosocial distress due to the cancellation was identified in some patients, particularly middle-aged women. Despite these results, confidence in the national health care system and in the treating orthopaedic surgeons was not affected.

The long road to recovery: at six months since the first COVID-19 wave, elective orthopedic care has still not fully recovered in Belgium

PURPOSE

The primary aim of our study was to investigate elective orthopaedic care during the first wave government-imposed COVID-19 lockdown and at four weeks and 21 weeks after resuming elective care. The secondary aim of our study was to evaluate the implementation of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA) COVID-19 Guidelines and Recommendations for Resuming Elective Surgery in the clinical practice of Belgian knee surgeons.

METHODS

We sent three anonymous online surveys to 102 Belgian Knee Society members (BKS) at times mentioned above. Addressed topics were: (1) participant demographics, (2) elective surgeries, (3) outpatient visits, (4) ESSKA Guidelines, (5) patient and surgeon safety.

RESULTS

During the COVID-19 lockdown, there was a decrease of 97% in elective knee surgeries and 91% in outpatient visits. At four and 21 weeks after resuming elective care, volumes were respectively 67% and 89% for elective surgeries and 81% and 91% for outpatient visits. Regarding ESSKA guidelines, 91% of surgeons had no COVID-19 testing prior to resuming elective care. Ninety-two per cent reported preoperative (< 72 h) patient PCR testing, and 45% gave preference to young patients without comorbidities. Seventy-two per cent did not use additional personal protective equipment (PPE) if a patient PCR test was negative. Forty-nine per cent continued to give preference to general anaesthesia.

CONCLUSION

Our study shows that elective surgeries and outpatient visits were almost completely interrupted during the COVID-19 lockdown and were still below normal at four and 21 weeks after resuming elective care. Regarding ESSKA COVID-19 guidelines, our study observes good compliance in preoperative patient COVID-19 testing, but lower compliance for preoperative health care personnel testing, patient selection, use of PPE, and locoregional anaesthesia.

Recommendations for resuming elective hip and knee arthroplasty in the setting of the SARS-CoV-2 pandemic: the European Hip Society and European Knee Associates Survey of Members

PURPOSE

The COVID-19 pandemic has disrupted the health care system around the entire globe. A consensus is needed about resuming total hip and knee procedures. The European Hip Society (EHS) and the European Knee Association (EKA) formed a panel of experts that have produced a consensus statement on how the safe re-introduction of elective hip and knee arthroplasty should be undertaken.

METHODS

A prospective online survey was done among members of EHS and EKA. The survey consisted of 27 questions. It includes basic information on demographics and details the participant's agreement with each recommendation. The participant could choose among three options (agree, disagree, abstain). Recommendations focussed on pre-operative, peri-operative, and post-operative handling of patients and precautions.

RESULTS

A total of 681 arthroplasty surgeons participated in the survey, with 479 fully completing the survey. The participants were from 44 countries and 6 continents. Apart from adhering to National and Local Guidelines, the recommendations concerned how to make elective arthroplasty safe for patients and staff.

CONCLUSION

The survey has shown good-to-excellent agreement of the participants with regards to the statements made in the recommendations for the safe return to elective arthroplasty following the first wave of the COVID-19 pandemic.

Resuming elective hip and knee arthroplasty after the first phase of the SARS-CoV-2 pandemic: the European Hip Society and European Knee Associates recommendations

PURPOSE

The Covid-19 pandemic has disrupted health care systems all over the world. Elective surgical procedures have been postponed and/or cancelled. Consensus is, therefore, required related to the factors that need to be in place before elective surgery, including hip and knee replacement surgery, which is restarted. Entirely new pathways and protocols need to be worked out.

METHODS

A panel of experts from the European Hip Society and European Knee Association have agreed to a consensus statement on how to reintroduce elective arthroplasty surgery safely. The recommendations are based on the best available evidence and have been validated in a separate survey.

RESULTS

The guidelines are based on five themes: modification and/or reorganisation of hospital wards. Restrictions on orthopaedic wards and in operation suite(s). Additional disinfection of the environment. The role of ultra-clean operation theatres. Personal protective equipment enhancement.

CONCLUSION

Apart from the following national and local guidance, protocols need to be put in place in the patient pathway for primary arthroplasty to allow for a safe return.
